This study reports the use of monodisperse Au nanoparticles (NPs) as a catalyst for growing silica nanorings (NRs) and nanowires (NWs). Combining spin coating and optical lithography strategies makes it possible to fabricate pattern-monolayer Au NPs that self-assemble on a 3-aminopropyltrimethoxysilane (APTMS)-modified silicon substrate. This can be used as a catalyst for the selective-area growth of silica NRs and NWs. Cathodoluminescence (CL) analysis reveals these NRs and NWs materials exhibit a blue-light emitting phenomenon. The novel optical properties of these materials are advantageous in applications for light-emitting devices with nanoscale dimensions.
